EDWVIN H. BURKS, OF TRENT, TEXAS.

ATTACHMENT FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 784,514, dated March '7, 1905.

Application filed October 13, 1904. Serial No. 228,318,

To all whom it may concern:

Be it known that I, EDWIN H. BURKS, a citizen of the United States, residing at Trent, in the county of Taylor and State of Texas, have invented certain new and useful Improvements in Attachments for Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in cultivators.

The object of the invention is to provide an attachment for cultivators whereby the shovel may be adjusted to plow a deep or shallow furrow.

A further object is to provide means for accomplishing this purpose which may be conveniently adjusted by the operator without dismounting from his seat or stopping the machine, thereby saving considerable time and labor over the method commonly employed in effecting such adjustment.

I/Vith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafterlnore fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a cultivator, illustrating the application of the attachment, showing in full lines one position of the adjustable parts and in dotted lines another position of the same and Fig. 2 is a front view of the parts shown in Fig. 1.

Referring more particularly to the drawings, 1 denotes the beam of a cultivator, on the upper side of which is mounted the drivers seat 2 and to the lower side of which is connected the usual standard 3. On the lower end or foot 4 of the standard is pivotally connected a boot 5, the upper bifurcated end of which is disposed on each side of the foot, as shown. The said upper ends of the boot project above the pivotal point of the same and have pivotally connected thereto a pair of rearwardly-projecting short parallel link-bars 6, the opposite ends of which are pivotally connected to the lower end of a hand-lever 7. Said lever 7 is pivotally mounted between a pair of rearwardly-projecting parallel bracket-bars S, secured at their forward ends to the standard 3, the rear ends of the same being connected to the standard by a segmental rack-bar 9.

On the hand-lever 7 is arranged a springprojected pawl 10, which is adapted to engage the teeth of the rack-bar i), and thereby hold the lever 7 and the boot 5 in their adjusted positions. The pawl 10 is connected to the lower end of a retracting-rod 12, the upper end of which is connected to a bellcrank lever 13, pivoted to the lever 7. adjacent to the handle of the same, in the usual manner.

The advantages of an attachment of this character over the method commonly employed for adjusting the cultivator-shovel will be readily apparent, as in most cultivators now in use it is necessary to stop the machine and remove and change one or more bolts in effecting the adjustment of the shovel, while in the attachment herein shown and described this is obviated and the shoe is given the desired pitch without the neces sity of the driver leaving his seat.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention,what I claim as new, and desire to secure by Let.- ters Patent, is

1. A cultivator having a standard provided with a supporting device, a lever pivoted to said supporting device, a boot pivotally connected to the standard and extend ing downwardly therefrom, and a link connecting said boot and lever, whereby the boot may be disposed at any desired angle by operating said lever.

2. A cultivator having a standard provided with a supporting device extending rearwardly therefrom, a lever fulcrunied to said supporting device, a boot pivotally connected to the standard, and extending upwardly and downwardly therefrom, and a link connected to said lever and said arm of said boot, for the purpose set forth.

3. In a cultivator, the combination With the standard of the same, of a bifurcated boot pivotally connected to the foot of said standard, rearWardly-projecting parallel bracketbars secured to said standard, a hand-lever pivotally mounted between said bars, parallel link-bars connecting the lower end of said lever and the upper end of said boot M.
